Ubuntu Networking :: Connection Gets Corrupted After A Certain Software Installation
Jun 26, 2011
Ubuntu 11.04 32bit TP-Link TL-WN821N which is listed HERE as supported using the ar9170usb driver.So I've done 4 fresh reinstalls and each time after a specific step following THIS guide my Wireless connection gets corrupted and does not want to work. The last time I did all the changes in small steps so I can catch the offending one and so after I've executed the code below and restarted my system the wifi went haywire:
Up until that point everything was working just fine and I was remotely managing my desktop using a Windows VNC Viewer and Ubuntu Remote Desktop. So could it be that this dkms (whatever that is) is causing the problems? Do I even need to install it for all the other software to work as it is not mentioned in any other bitcoin mining guides? I would like to stress out that my connection is configured properly and I am 100% certain of that - as I said it is working like a charm up until the point of executing the commands above and restarting.
Any suggestions as the last 3 days have been a nightmare trying to figure out what's wrong after each fresh installation. P.S - The guide says to execute sudo aptitude install dkms but I guess the aptitude package is not installed so I ran sudo apt-get install dkms instead. If that makes any difference?
I'm COMPLETELY new to linux. I"m running Ubuntu 9.10 and TRYING to install Devede. I have tried the Terminal, Synaptic Manger, and the Add/Remove and still keep getting this same error. I'm running a regular 32 bit Pentium 3 process to test if I like Linux or not. this is what it says: E: /var/cache/apt/archives/libavcodec-extra-52_4%3a0.5+svn20090706-2ubuntu3_i386.deb: corrupted filesystem tarfile - corrupted package archive this is not a DUAL boot computer either.
Being an Ubuntu enthousiast (both professionally as well as at home), I upgraded my home server from 9.10 to 10.04 yesterday. It runs kvm with only 1 vm. Host and vm we're both ubuntu 9.10 64bit. I upgraded both to 10.04. So far so good. Also did reboots to load the new kernel image.
For data storage I have a large (6,35TB) XFS partition. This partition is exported to the vm as a block device (vdb). This morning I noticed the vm has crashed. The XFS partition (mounted as /home) was shut down. Is this just bad luck? Or is it 10.04?

I tried booting with an older (2.6.31) kernel, but didn't help. Can I safely run xfs_repair without causing any more damage?
All disks in this system are attached to an Areca hardware raid controller configured in Raid5 and has been operating for months now without any problem.
I'm trying to install a package (mythTV backend - but im sure the package is not at fault) and I keep getting this errorcorrupted filesystem tarfile - corrupted package archiveNew build - ubuntu lucid 32bitI think it might be a hardware fault memory/hardrive/motherboard or somthing to do with an error in /home/ partition filesystem.To be honest im not sure and its driving me mentalWould consider anyones input on possible causes of a Corrupted filesystem. Tried complete deleting (including cache) and reinstalling the package.force fskchk , restarted = nothing.Error checked the harddrive = nothingfrustrated as this is only the latest error in a series of problems ive been having with ubuntu on this build.
I've just tried installing drivers for my laptop (sis 671) and now my desktop gfx are corrupt. Any idea how I can recover? (eg delete xorg.conf).Recovery mode is corrupted, command prompt boot is really limited and I can't figure it out.
Yesterday all my troubles seemed so far away, because I've been using working system with Windows 7 & Ubuntu 10.10, but last night I decided to update to 11.04 from update manager. So, when upgrade was done, I rebooted and saw something like this:
"grub_env_export not found grub rescue > "
Do I have a problem with MBR? Will it help, if I load from Ubuntu live cd and try to reinstall grub?
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. E: _cache->open() failed, please report.
Running the requested command in terminal, I get
ubuntu@ubuntu:/var/lib/dpkg/updates$ sudo dpkg --configure -a dpkg: error: failed to open package info file `/var/lib/dpkg/updates/0001' for reading: No such file or directory ubuntu@ubuntu:/var/lib/dpkg/updates$ ls -l
[code]...
Also tried to move, copy and rename the file and also to delete the updates folder with rmdir. Also tried rm -i * but it seems there is only the one file in the folder. The only strange result is the "total 4" when I run the ls -l command:
I just uploaded JPG pics from a Win XP, through shell, on my FTP.When I downloaded them back (to a UNIX machine), they were all currupted and unreadable !After some researches, I found that Win XP's shell works by default in ASCII mode.
The computer that I have Ubuntu/Karmic just recently installed on, has 2 hard drives. Primary is Ubuntu, secondary is win95b. After the Karmic installation (which went perfectly), I now find that when I boot to the secondary drive, the MBR for win95b is reporting it is corrupted. I can use win95b, BUT it runs in dos compatability mode, and there are no CD drives showing, despite the fact that BIOS reports 2 cd drives. Can GParted fix the corrupted MBR on the win95b hard drive?
I just ran an update of ubuntu 9.04 to 9.10 and now the "startup" splash and the login splash is gone. Instead I see the terminal during bootup and the login prompt is some strange sparse login screen looking like it was taken from some old CDE GUI. What has happened and how do I fix it?
I can also add that while upgrading I chose to let the menu.lst remain untouched which turned out to be a bad mistake. So I added the following lines manually to compensate for my mistake.
But that didn't resolve my problems. I also tried the following without success:
After loging myself out and pressning ALT+F1/ALT+F7...
I have been trying to get the live image of 10.4 to work on my machine, however I keep running into video corruption issues. When I try to run the live image, from a CD or USB stick, it shows the loading screen fine and the bars underneath the logo move and look fine. Then it seems as though it has loaded and goes to desktop, but it only shows a corrupted image of the loading screen. After a few seconds there seems to be some sort of intro sound playing, however it is very scratchy/corrupted. I'm not sure what the issue is and I have tried 32 and 64 bit versions.
I have also tried installing via Wubi and get the same results. I'm really at a loss of how to correct the problem. Not sure if it is a video driver issue, or some other issue. I also can't seem to find a safe graphics mode to try and work around the problem. My specs are DFI Lanparty Expert nvidia 7800 gt 2gb ram x-fi sound card
before i proceed,I'll like to say that I'm a complete newbie, but enjoying my time with Ubuntu.
Recently, due to hard disk failure, some of the System files got corrupted, I have no idea to which files, but booting Ubuntu from the latest kernel is not working, instead I have to select the previous version from the grub screen.
How to recover these files? Is there a way by which Ubuntu automatically scans and repairs the system files.
Recently I am trying to install the latest Ubuntu / Xubuntu but after the kernel messages the display becomes corrupted. The machine is a Clevo laptop with the dreaded SIS 671 / 672 chipset. The Ubuntu 8.04 is working flawlessly. Any other version I get several problems and depending on the mood of the system I get a vertical running display ( not readable ) or a left horizontal displaced screen (readable) ...
I tried more tan several CDs ranging from 9.01 to 10.10 both Ubuntu or Xubuntu. What is the plainest (simpler ) VGA mode in order to install it? I have tried vga=normal and even VGA =3 with no success. With the latest Ubuntu 10.10 I get another problem it simply does not recognize the HDD / SSD. I have traced the SSD problem with the sata_sis module in kernel 2.6.35 and up... Other distros have the same problem ...
I have recently done a clean install of Ubuntu 10.04. Since then I have had no end of trouble with Openoffice 3.2.
When I open any office app, the text on the menus is corrupted and has lines going through it. I've included some screenshot to show what I mean.
Also, sometimes when I open an Excel spreadsheet my entire system crawls to a standstill and it can take anything up to 10 minutes for it to respond again. Not even the mouse cursor will move. If I reboot the PC and open the same document it will sometimes be just fine. It is very random.
So far I have tried uninstalling and reinstalling openoffice.org from apt-get, but this hasn't fixed the problem.

I originally wanted to dual install 10.10 64 Ubuntu with Windows 7 64 RAID 1 HP PC, but RAID got corrupted and I could find no fix online except using fakeraid unsupported software. The whole thing blew my muind. I gave up after 4 or so reinstalls of windows 7 to fix RAID. So I decided to install a dual boot 10.10 Ubuntu i86 with my old WinXP i86. I kept getting these errors at boot up: unknown filesystem, file not found, out of disk, no such partion and so on. I tried just about every grub reinstall I could find, including article here: "Recovering Ubuntu after Installing Windows."
After a number of tries my friend installed Ubuntu successfully, but then when I installed windows xp I am stuck here, again. I did do the Reload grub tutorials again as well. I may just give up on WinXP and have my friend reinstall Ubuntu for me.
I downloaded latest Ubuntu version 10. I bruned it to CD disc. I run WUBI.exe. Some files copied to the hard drive, but the error message interrupted in the middle of the installation process. It said unable to install -- permission denied. I don't see what is wrong. My Windows XP is full administration control. All the files should be able to write to drive c without any problem. What is the cause? Could files in ISO image be corrupted?
i had ubuntu installed on my computer via wubi inside my windows 7 OS..after a while something went wrong with the partitions magic stuff and windows 7 got corrupted but ubuntu kept working Love ubuntu for that.since i had my stuff backed up and saved in ubuntu i thought i could make a backup off the root.disk file and reinstall windows and that what i did but then i installed ubuntu again via wubi but replaced the new root diskk with the old one that i had backed up.but now it says it cant find disk :O .so it takes me to a shell i seriously need to get that root disk to work or ima loose really important stuf.
I have a Windows XP/Windows 7 dual boot system. My problem: [URL]. I follow these instructions to the letter, the live "CD" works fine - using a USB stick, I do not have a DVD drive, in- or external -. When I try to install Ubuntu from the live system, it corrupts my master boot record, I get the Error: No Such Device #####################. After I fixed this I tried to install Ubuntu under windows, using the same usb's wubi installer. The install completes, I reboot, and after selecting Ubuntu in my boot menu, I get that likewise well known error with wubildr.mbr [URL]
Rebuilding the USB stick doesn't make any difference, it behaves the same way. The wubi installer has the very annoying habit of downloading the iso during the installation procedure every time, I don't know why I can't just select the iso downloaded in the first step of the above link. This way I cannot check any md5 because I have no idea where it downloads the iso. What should I do to get Ubuntu working? Reinstalling any of my Windows systems is not an option, it is every time like gambling, I am using the same installation files, but sometimes the result is just not the same.
My HP Netbook crashed. The Windows XP system files corrupted and Windows absolutely will not run. I planned on using Ubuntu to recover it, and then install Ubuntu permanently to save it in the future. Before you ask, every other utility has failed on me. UBCD included, which did nothing but provide me with errors upon errors just trying to run it.
The netbook has no CD drive.The only internet around is a wireless signal... my netbook has a broadcom wireless card that is never recognized. I'm using someone elses working laptop to connect online and get things I need, make boot devices, research for help, etc.This laptop has barely any hard drive space. Currently it has 1 gb remaining for doing anything.I have three flash memory devices:2 gb SD card. My netbook refuses to recognize it as a boot device.2 gb flash stick (that's actually an mp3 player). My netbook refuses to recognize it as a boot device.512 mb flash stick. This DOES work as a boot device.
So far my 512 mb flash stick has run Damn Small Linux and Ubuntu Minimal on my netbook. Of course, both are useless because the netbook cannot access internet, nor does either OS recognize my wireless card. This flash stick is, obviously, too small for a regular Ubuntu installation or any other Linux distribution that can help (as far as I know).
So, in order for this to work, I have to be able to do one of the following:
Install Ubuntu from a different OS, like Damn Small Linux or something small enough to boot on my 512 mb stick. Ubuntu can be put on one of the other, larger devices, maybe to be accessed for installation. No idea how to do this, let alone safely.
Install Ubuntu Minimal OFFLINE. This question was asked multiple times on these forums and none were answered. Is there a way to run minimal, and use offline sources for the install?
Get the normal Ubuntu installer under 500 mb. Its overwhelmingly frustrating that I'm just barely unable to do this. I've read of Ubuntu Customization Kit, which ended up being lots of useless files and reams of gobbldegook. I've heard Ubuntu is packed with additional, nonrequisite software which makes it so large. Why can't there be a halfway version between normal and minimal?? Not everyone has internet and not everyone has a CD drive or large USB stick! Is there a way this can be accomplished? Does this version exist?
I have limited time and resources. Before you ask, no, I cannot afford a larger USB stick. I'm pinching pennies right now and there's nowhere near here that sells them anyway.
System gets corrupted when I abort a kickstart installationI have a simple kickstart installation of CentOS 5.5 (same issue on 5.3)The only user interaction is the partitioning screen.if, in my cfg file, I state :-

I download the live 64 and burned it to a disk after it burns to the disk Brasero checks and says "error some files could be corrupted." I burn it slowest burn same thing happen. I downloaded thinking I had a corrupted download. Same thing happen. I never had a problem burning iso until now. What am I doing wrong?
I was browsing the available packages to install the weather indicator and noticed that a network indicator was available. apt-get said that it needed to install 'connman' and remove 'network-manager' and 'network-manager-gnome' in order to install the network indicator. I foolishly assumed it knew what it was doing so I went ahead and performed the installation/removal and restarted the computer.
Now I cannot connect to the internet. I only have an ethernet card for connection to the internet, no wireless or otherwise. The configuration I use is not DHCP, but a manual settings of address/subnet/gateway and name servers
When I try to set the network values through the network indicator some of them do not stay set. The gateway value appears to be set, but then after closing down the indicator window completely it comes up with the value 'Modified'. The DNS servers is the only other value that does not stay set, but it only changes to be blank. The connection never works.
So, I downloaded 'network-manager' and 'network-manager-gnome' on another computer, transferred the packages by USB, and reinstalled them (uninstalling connman and the network indicator). But the network connection remains broken. At least with 'network-manager-gnome' the values I set stay set, they just don't work anymore. I've tried editing /etc/network/interfaces to previously working values directly, but they do not seem to have any effect either. The connection no longer works.
I really do not care if I use the network indicator or not at this point, I simply want the network connection to work properly.
Edit: I realize I forgot to say that I'm using Ubuntu 11.04 (upgraded from 10.10). The network card is the "Integrated Broadcom 57780 Gigabit Ethernet controller".
I'm trying to create a PAN (Personal Area Network) using a laptop (Siragon ML-1040) and my desktop computer, but I get the Connection Refused (111) error.
Blueman doesn't detect any network service between the two computers unless I start PAND on one of them and then it detects the NAP service. That, only after I enable the NAP/Workgroup services on the Services submenu in Blueman. However, it doesn't work neither with the NM plugins or without them (dhclient and that other one I can't remember the name of).
Any clues over here? I'm using pand 4.91 and blueman.
Its a case of ".... wireless network connection active but still not internet connection .."I am using WEP - 128 key ... Works when I connect directly using ethernet cable ... but not wireless (pci and wireless router)
I'm trying to do a SSH connection between my home and work PC both machines are running ubuntu 10.04. I have read all the comunity documentation at [URL] from Work PC. I went on to the web site what is my ip address and noted down the number, From Home i opened a terminal and typed: pnig (ip address). to which their was no reply, now i'm assuming i need to configure the works router to except connection requests, is this Correct?
Also what information do i need from my works network and how do i get it? I understand that I need the routers expernal ip address, but how do i referiance a specified computer after that address? What program do i use in ubunu and how is that information applied to it?
When I have video running and the video stops, I see that the connection is destroyed in about 5 seconds, which is what I want. If, rather than stopping the video, I pull the plug, I have seen it take 350 and 380 seconds before the connection is destroyed. Why is there such a large difference in the time to destroy a video connection between stopping the video and pulling the plug on it when using net filter connection tracking? How can I shorten the time for the connection to get destroyed when pulling the plug?
I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.
